“Goat” From Concise Bible Dictionary:

The well-known animal, regarded as clean under the Levitical economy, and having a large place in the sacrifices. Goats formed an important item in the property of the patriarchs. In Daniel’s prophecy of the kingdoms, that of Greece was compared to a “rough he goat,” but with a notable horn between his eyes (Dan. 8:5, 8, 21). The goats, in the sessional judgment of the living nations, represent the lost, in contrast to the saved, who are compared to sheep (Matt. 25:32-33). THE WILD GOATS were larger animals and lived on the mountains (1 Sam. 24:2; Job 39:1; Psa. 104:18).
